On a Thread: page (not sure if that happens also in the discussion page):
If you reply to a thread that has more than 5 nested messages, when you save the message, it disappears, and then a tiny notification at the top of the thread says that this thread has new messages. This is wrong, your own reply should be visible when posted. Specially since we're on a Thread: page which should display all messages.
When clicking on that notification, it reloads the contents and then only the first 5 messages appear again, plus the link to display more messages, like if we were on a discussion page (wrong again). And the contents contain the thread header: title and links to history, rename, watch/unwatch...
This is very confusing for new users. See [1].
This happens on www.mediawiki.org
Maybe the api doesn't know if we're on a thread page or a discussion page.
